Mount Rainier at 4,393 meters (14,410 feet) the highest peak in the
Cascade Range is a dormant volcano whose load of glacier ice exceeds
that of any other mountain in the conterminous United States. This
tremendous mass of rock and ice, in combination with great topographic
relief, poses a variety of geologic hazards, both during inevitable
future eruptions and during the intervening periods of repose. ...
This report (1) explains the various types of hazardous geologic
phenomena that could occur at Mount Rainier, (2) shows areas that are
most likely to be affected by the different phenomena, (3) estimates the
likelihood that the areas will be affected, and (4) recommends actions
that can be taken to protect lives and property. It builds upon and
revises a similar document prepared by D.R. Crandell in 1973. Our
revision was motivated by the availability of new information about
Mount Rainier's geologic history, by advances in the field of
volcanology, and by the need to assess hazards in a more quantitative
manner than in Crandell's pioneering report.
